Case Type   : 多节点写入
Case Name   : 备机在触发器中执行INSERT/DELETE/UPDATE语句及DDL语句
Create At   : 2023/1/6
Owner       : @li-xin12345
Description :
    1.修改enable_remote_execute参数值为on
    2.备机在触发器中执行INSERT/DELETE/UPDATE语句及DDL语句
    3.备机查看日志打印
    4.环境清理，恢复参数
Expect      :
    1.修改成功
    2.执行成功
    3.日志记录建立连接、转发给主机、接受执行结果等libpqsw信息
    4.环境清理成功，恢复参数成功
History     :
    Modified by @li-xin12345 2023/1/16:添加等待时间，等待触发器执行完成
    Modified by @li-xin12345 2023/3/15:研发代码变更，libpqsw日志打印增加线程号，优化断言以适配新代码
    Modified by @li-xin12345 2023/3/21:延长等待时间，等待主机执行完成并返回结果给备机
